This guide requires knowledge on:

• maven
• git
• eclipse
• querydsl
• wild fly

We will show you how to modify the javaee7-archetype project to integrate querydsl. For those who do not know, it is a library to unify queries in java. What I like more about it is that you can fluently construct your api. For more info refer to: http://www.querydsl.com/static/querydsl/4.1.3/reference/html_single/

Follow this guide to setup your project:

Take note, of the arquillian configuration, as we will need it later.

Since I am lazy :-), I will just provide the test project that I have created in GitHub: https://github.com/czetsuya/JavaEE7-QueryDSL-Demo

Things you should take notice:

• In resources I have added a JPAQueryFactoryProducer:
  

  @Produces
   public JPAQueryFactory produceJPQQueryFactory() {
    return new JPAQueryFactory(em);
   }
  

• Note that I have modified Member entity, added a BaseEntity and Identifiable interface.
• I have added a new package: com.broodcamp.javaee_querydsl_demo.repository and the classes inside it.
• I have also modified: MemberRegistrationTest, so that we can run the arquillian test correct.

To run arquillian simply execute this command inside your project in the terminal:

>mvn clean test -Parq-wildfly-managed

The test should run without error.
